GRADER AND DITCHER.

SPECIFICATION forming part of Letters Patent No. 357,522. dated February 8, 1887.

' Application tiled May 24, 1886. Serial No. 203,160. (No model.)

.T all whom, it may concern:

Be it known that I,. CORNELIUs COOK, a citizen of the United States, residing at Fre-y mont, inthe county of Dodge and State of Nebraska, have invented certain new and useful Improvements in Graders and Ditchers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and toletters or gures of reference marked thereon, which forni a `part of this specification.

Figure l of the drawings is a plan View. Fig. 2 is avert/ical longitudinal section on line :c fr, Fig. l. Fig. 3 is a transverse section on line y y, Fig. l. Fig. 4 is a similar section Onlinez a, Fig. I; and Fig. 5 is a detail View of the cutting-wheel.

My invention relates to graders and ditchers; and it consists in the construction and novel combination of parts, as hereinafter described, and pointed out in the claims.

Referring by letter to the accompanying drawings, A designates the main frame, which is rectangular in forni, and is provided in its side rails, B, with mortises M, made vertically through it to receive the perforated standards M', tothe lower ends of which the sled-runners M2 are secured and provided with proper metallic soles. Bolts M3 are passed laterally through the mortises in the side rails, B B', and through any of the desired perforationsl? in the vertical standards M', to give the main frame the proper or desired elevation above the runners, so that buta small portion of the cutting-cylinder C will be in operation when a shallow ditch is to be made.

The cutting-cylinder C is mounted on the main or driving .shaft C', and is provided with a wide peripheral or rim flange, C2, which extends rearwardly from the verticaln front facel Of the cutting-cylinder, and is provided on its inner face or periphery with buckets or iifters C4, which carry the loosened dirt up and deposit it upon a stationary inclined sheetmetal apron or chute, D, which latter directs t-he dirt to and delivers it upon the endless carrier E.

The cutting-cylinder O has two diametrically-opposed radial slots, S S', in its vertical face, each. of which is provided with la cutter or blade, Swhich projects slightly in advance of one edge of the slot in which it is located. The rim-{iange C2 of the cutting-'cylinder C is provided with aslot, S,through which ablade, 'Si riveted to said flange, projects, and these several knives serve to loosen the dirt as the machine is propelled along the line of the ditch.

The lower half of the cutting cylinder C is closed by a stationary seinicircular sheet, F, of metal, which is secured by arms F to the sidel rails, B, 'of the lmain frame and prevents the dirt from falling from the buckets or lifters CB as it is being carried up to bedeposited on the inclined chute D. This metal chute D is secured to the upper edge of an inclined met-al sheet, G, the lower edge of which sheet G is secured to the upper edge of the stationary Semicircular sheet F, said sheet G extending inwardly nearly to the vertical front face of the cutting-cylinder C.

An auxiliary frame, H, has the inner ends of its arms secured in a recess, H', in the upper face of the side rail, B, and' is provided at its Outer end with a roller, H2, over/which the outer portion of the endless carrier E runs, the inner portion of said endless carrier Erunning over a pulley, I, secured to the l'ront end of the horizontal shaft l', rotating in bearings I2 I2 at the lower ends of the inclined arms l3 I3, secured in the inner face of the side rail, B', of the main frame. The shaft of the pulley H2 is provided on its rear end with a sprocketwheel, K, and this sprocket-wheel K is connccted by a sprocket-chain, K', to a sprocketwheel, K2, on the drivingshaft C. The driving-shaft C' is provided with a sprocket conepulley, K3, im mediatelyin rear ofthe sprocketwheel K2, and this sprocket cone-pulley K3 is connected by a sprocket-chain, L, with a sprocket cone wheel or pulley, L', on the rear end of a shaft, M4, having bearings in boxes M5 MG, secured upon the upper face of the side rail, B'. At its front end the shaft MA1 is provided with a miter gear or pinion, N, which pinion 'N engages a miter gear or pinion, P', on the end of atransverse shaft, Q, workingin bearings in boxes Q', and having at its inner end the drum or windlass R, upon which the draft-chain E', provided with the grapplinghook B", is wound as the machine is propelled forward.

The machine is propelled by two vertical steam-engines, d a, which drive a worni, I), the latter being connected with a worm-wheel, c, on the driving-shaft C.

7s designates the steam-boiler, Z the fuelbox, and Imthe water-tank, which are located on the platform of the main frame:

The plow a', in front of the `journal of the cutting-cylinder C, is to open a way for the box Y, in which the front end of the shaft C' is journaled.

The machine is to be adjusted to eut a ditch of the desired depth, and ordinarily its limit is five feet depth.

Near the rear end of the main frame, just inside of the rear eross-timber, I provide a downwardly-curved guard, X, of the same are as the cutting-cylinder, the object ofwhich is to prevent the runners from droppinginto the ditch, the said guard X ruiming in the ditch for this purpose.

Having described this invention, what I claim, and desire Vto secure by Letters Patent, 1s-

l. The combination, with the main frame mounted on vertically-adjustablc run ners,and provided with the cutting-cylinder on the main driving-shaft provided with a wormwheel and the cone sproeketswhcels, of the metal apron within the cutting-cylinder, the y sproeket-wheels on the horizontal shafts, and the Worm-wheel connected to the engines, substantially as specified.

2. The combination, with the main frame provided with the cutting-cylinder,and mechanism, substantially as described, for operating it, of the vertically-adjustable runners connected to the perforated standards .working in niortises in the main frame and secured in place by adjusting-bolts, substantially as specified.

3. The combination,.with the main frame mounted on adjustable runners, ofthe cuttingcylinder mounted on the driving-shaft and provided with the radial and peripheral knives, the metal apron and guard, and the endless carrier, substantially as specified.

4. The combination, with the main frame,

vand the shaft of the eutting-cyliinler supported in bearings on the main frame, of the opening-plow secured in front of and over the front bearing of the main shaft, substantially as specified.

The combination, with the main frame and cutting-cylinder,and mechanism, substantially as described, for operating said cuttingcylinder, of the rear guard having its are corresponding with the lower arcfof the cuttingeylinder, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CORNELIUS COOK.
